IMPROVEMENT IN MACHINES-FOR MAKING TRUNK CORNER-CLAMPS Specification forming part of Letters Patent N 0. 187,267, dated February 13, 1877 application filed January 10, 1877.

To all whom it may concern Be it known that we, WILLIAM B. GOULD, of Montrose, in the'county of Essex and State of New Jersey, and NIKOLAUS FEIOK, of N ewark, in the county of Essex and State of New Jersey, have invented a new and Improved Machine for Making Trunk Corner-Clamps, of which the following is a specification:

Figure l is a vertical longitudinal section of our improved machine for making trunk corner-clamps. Fig. 2 is a similar view thereof, showing the parts in a different position. Fig. 3 is a plan view of the lower or bed part of said machine. Fig. 4 is a vertical transverse section through the shaping-punch and mold of the same.

Similar letters of reference indicate corresponding parts in all the figures.

This invention has for its object to produce a machine for cutting, perforating, bending, and bulging, in one continuous operation, the wrought-metal blanks used in the manufacture of bulging corner-clamps for trunks. It consists in the novel combination and arrangement of parts for effecting the desired result, all as hereinafter more fully described.

The corner-clamps to be produced by this machine are V-shaped pieces of flat metal, bulged at the corners or sides to form projecting hollow beads, and perforated near the ends to receive the nails or screws that fasten them to the sides of a trunk.

In the drawing, the letter A represents the stationary bed of our machine. Upon it is secured, by suitable bolts or screws, a table, B, which, in turn, supports a detachable die or plate, 0. This plate has a vertical aperture, a, of the size and shape of the blank to be cut out, and is, in front of this aperture a, provided with a series of smaller holes, b b, for purposes hereinafter pointed out. Directly behind the aperture a is formed, on the plate 0, a projecting ridge or stop, d.

We prefer to secure the die or plate 0 to the table B by providing the latter with projecting dovetail-shaped lugs e c, and fastening the plate 0 therein by means of a key, f. This enables us to remove the plate 0 and replace it by another having a larger or smaller aperture, a, or having the holes b differently disposed. Beneath the aperture a is forme on the surface of the table B, a recess, 9, fc

receiving theblank that is dropped throng such aperture. D is a slide, arranged lengtk wise in a groove of the table B, on a level wit the surface thereof, and higher than the fac of the recess g. Rails h h extend from th table B, and connect the same with the ele vated parts ofa female V-shaped die, E, tha

is placed near one end of the bed A. Th surfaces of these rails are on a level with an( constitute continuations of the surface of thr recess 9. The inclined faces of the die E, a or near their junction, have cavities formed it them. The slide D has a downwardly-pro jecting pusher-piece or hook, 2', formed on it: end, as shown. Reciprocating motion in a horizontal direction can be imparted to the slide D by suitable means. (Not shown.) Fis a vertically-reciprocating plunger, moved by suitable machinery, and placed over the plate 0 and die E, in manner indicated in the drawing. This plunger F carries a series of pendent pins, j j, above the several apertures 11 b, and of a size to fit the same; also, a block or cutter, l, of the size and shape of the hole a. directly above said hole; also, a male V- shaped punch, m, directly above the die E, and of a size and form to fit the same, all as indicated in Fig. 4.. The punch m has bulgelike projections n n to fit the cavities of the die E. Instead of making the female die stationary and moving the punch, the latter may be placed at the bottom and the die caused to move; but we prefer the special arrangement shown. G is a blow-pipe leading from a suitable pair of bellows or pumps into or toward the hollow of the die E, for the purpose of blowing it cleanafter every stamping operation.

The operation of the apparatus is as follows: A plate of sheet metal of the requisite width and thickness is first placed on the plate 0, over the holes I) b,- the plunger then descends, and by means of the pinsjj it punches holes through such plate, which are to be in the ends of the corner-clamp. The plate is next, after the plunger is elevated, shoved against the rib or stop d on the plate 0, and the plunger once more brought down, cutting th its cutter l a blank of the desired shape it of the metal plate, and pushing the same to the recess g. The pins j meanwhile perrate another part of the metal plate in the :sired place. After the plunger has next :en elevated the metal plate is again pushed gainst the rib d, and the slide D is moved to illltO the die E, as in Fig. 2, and by this mo- .on also forms the desired hollow beads on he clamp. After the plunger has again been levated, the slide D is again moved to carry nother blank into position on the die E, and 0 push with its hook-like projection i the ompleted corner-clamp H out of the die, as learly indicated in Fig. l.

The motions above described are then repeated with the result stated. After a completed clamp has been discharged from the die, a pufi of air is blown through the pipe G into said die to clear the same of all scales and impurities that may have been deposited therein by the punching process.

We claim as our invention- 1. The combination of the die-bed A, provided with the die-plate G, perforated as described, and the V-shaped die E, with the plunger F, provided with cutter l,pins j, and punch m, substantially as described.

2. The plate 0, made with the holes b and perforation a, and with the rib d, in combination with the pusher-plate D and rails h, substantially as specified.

3. The pusher-piece i, placed on the blankpusher D, to operate in combination with the die E, substantially as herein shown and described.
